Zusammenfassung:	PURPOSE:To obtain a zinc alkaline battery whose hydrogen gas evolution from amalgamated or non-amalgamated zinc or zinc alloy used as a negative electrode is remarkably retarded by adding a specified amount of sulfolane as an inhibitor in an electrolyte comprising alkaline aqueous solution. CONSTITUTION:In a zinc alkaline battery using alkaline aqueous solution as an electrolyte and zinc or zinc alloy as a negative electrode, 0.2-5.0wt% sulfolane based on the alkaline aqueous solution is added to the electrolyte. Even when zinc alone is used as the negative electrode, the amount of hydrogen gas evolution is retarded. When zinc alloy containing one or more of lead, cadmium, indium, thallium, gallium, and aliminum is used as the negative elec trode, the effect is increased. When amalgamated zinc or amalgamated zinc alloy made of the zinc alloy is used, hydrogen gas evolution is furthermore decreased.
